Support for Intel Keem Bay Offload and Crypto Subsystem (OCS) AES and
SM4 cipher hardware acceleration for use with Crypto API.
Provides HW acceleration for the following transformations:
cbc(aes), ctr(aes), ccm(aes), gcm(aes), cbc(sm4), ctr(sm4), ccm(sm4)
and gcm(sm4).
Optionally, support for the following transformations can also be
enabled: ecb(aes), cts(cbc(aes)), ecb(sm4) and cts(cbc(sm4)).
